L'atelier du 27 mars en préparation...

Objectif général : se familiariser avec un ESP32 sur HA, via ESPHome

Fournitures, un ESP32 standard, un ESP32 SIM800 (SMS et appels)

- installation de ESPHome sur HA

- connexion d'un ESP32

- installation de programmes de test : serveur web, allumage d'une LED, envoi et réception de SMS, etc.

- création d'automatisations utilisant les ESP 32
